The coil fixing device includes a door frame, a center rod and a clamping block. The door frame includes an L-shaped fixed end and a movable end. The fixed end is movably connected to the movable end. One end of the center rod is fixed to the fixed end and the other end extends horizontally. The clamping block is installed on the movable end. A pressing sleeve is provided on the center rod. The clamping block is a truncated cone with an annular groove. A slider is provided at one end of the movable end and is placed in the annular groove.
